The setting requirements and details of the following "condition data"[Da.16] to [Da.19] setting items differ according to
the "[Da.15] Condition target" setting.
The following shows the [Da.16] to [Da.19] setting items corresponding to the "[Da.15] Condition target".

: Setting not required
*2
, **: Value stored in buffer memory designated in [Da.17]
*2 Setting value invalid Use the initial value or a value within the setting range.
*3 Comparison of

and

is judged as signed values.
Refer to

Page 176, Section 5.5 for information on the setting details.
*4 The setting value of start axis (the axis which executes positioning start) should be "0". If the setting value is set to other
than "0", the positioning data set in [Da.18] Parameter 1 and [Da.19] Parameter 2 is given priority to be executed rather
than "[Da.12] Start data No.".
Judgment whether the condition operator is "=" or "

" at the wait start:
Judgment on data is carried out for each control cycle of the LD75. Thus, in the judgment on the data such as current
feed value which varies continuously, the operator "=" may not be detected. If this occurs, use a range operator.
Remark
The "PLC CPU memo area" can be designated as the buffer memory address to be designated in [Da.17].
